John Frieda mousse, particularly the volumizing one, turquoise, in case you feel inclined, don't go there.
It has taken me 3 cans of the stuff to realised that you must be endowed with the strength of flipping Hercules to get the merest dribble out the nozzle thing.

They gave up when I took the last one to Boots and asked if there was a knack.
There isn't, they refunded me.
